Costs
Corridors can be expensive to plan out and put into action. For example, Daniel Simberloff et al. states that “a bridge that would maintain a riparian corridor costs about 13 times as much per lane-mile as would a road that would sever the corridor.” He also states that maintenance of a corridor would be much more costly than refuges for endangered species. It would simply be easier to move animals between refuges than to buy land, install a corridor, and maintain it. However, where the goal is not just to preserve a few large animal species but to protect biodiversity among all plants and animals, then habitat corridors may be the only option. Corridors are going to be expensive to implement no matter what, but it does depend on the type, location, and size, which can all vary to a great degree. With the lack of field data on the effectiveness, many agencies are not willing to consider putting in corridors.

Famous quotes containing the word costs:
“To exercise power costs effort and demands courage. That is why so many fail to assert rights to which they are perfectly entitled—because a right is a kind of power but they are too lazy or too cowardly to exercise it. The virtues which cloak these faults are called patience and forbearance.”
—Friedrich Nietzsche (1844–1900)
“Like cellulite creams or hair-loss tonics, capital punishment is one of those panaceas that isn’t. Only it costs a whole lot more.”
—Anna Quindlen (b. 1952)
“It is commonly said by farmers, that a good pear or apple costs no more time or pains to rear, than a poor one; so I would have no work of art, no speech, or action, or thought, or friend, but the best.”
—Ralph Waldo Emerson (1803–1882)
